OPC-UA

Cloud Logging via OPC-UA is supported on the IXrouter2 in firmware 2.5 and up, and on the IXrouter3 in firmware 3.0 and up. Please upgrade your firmware if you are running an older version.

The first step in Cloud Logging is setting up a data source. This is done by selecting a communication protocol and defining the variables. This article shows you how to do this for communication via OPC-UA.

Select a communication protocol

You first have to select a communication protocol. This is the protocol that the IXrouter will use to communicate with the target (i.e. PLC).

Go to [Devices] in the main menu, select the concerning device, open its [Services] tab, and press [Add service].

Name the target(i.e. PLC1), enter the target's IP address, and press [Next].

Select your service type: [Data source].

Select the communication protocol "OPC-UA". The port number will automatically be filled based on the selected protocol (port 4840 for OPC-UA). Select the authentication type and enter your credentials if required. Press [Add].

Add variables

Once you've added a Data Source and selected a communication protocol, you can start adding variables. This is done in the configurator tool, specifically designed to quickly add, duplicate, import, export, and remove variables.

Go to [Devices] in the main menu, select the concerning device, open its [Services] tab, and edit the target's services.

Import variables from a file (or device)

You can easily and effortlessly copy variables from one device to another by exporting the concerning variables (view the "Manage variables" part of this article) and then importing them in your new device. Alternatively, you can manually prepare your variables in the required CSV format to load them all at once into your configurator. The CSV file structure is explained in our "Import variables: CSV file structure"-article.

When you press [Import from CSV-file], you'll see a browse window.

Select a CSV file to import and press [Open].

When the file has been read, press [Add] to add all variables to your data source.

Temporary disconnect

After this next step, the config push, the device will temporarily disconnect to reconfigure its network settings and will automatically reconnect. This may take a minute.

Test variables

The test utility is used to check if all the added variables are set correctly. It shows the status of every variable and displays the variables' latest values if everything is configured correctly. If not, it'll show an error message.

Required firmware version

Support for the test utility was added on the IXrouter2 in firmware 2.11, and on the IXrouter3 in firmware 3.7. Consider upgrading your firmware if you are running a older version.

In the configurator press [Run test].

A connection will now be set up to stream the data directly to your computer, using:

Port

Transport protocol

Application protocol

443

TCP

WebSocket

When the connection is set up and all variables are set correctly, it should look like this:

Unexpected result?

If the test utility shows unexpected values, please check if the addresses and data types of all variables are entered correctly.

If you get no data at all, please also check that the above listed port and protocols are not being blocked by your computer's or company's firewall.

Manage variables

You can view all defined variables in a list view or table view . Multiple variables can be selected by pressing the icon on the left, or you can select all by pressing [∙∙∙]. These can then be removed , duplicated , or exported to a CSV file .
